kindly, brought his dinner to him every day, and did all she could to make him goodnatured and comfortable. But nothing seemed to make him any better; and one day, when Theeda had made him let go of a prawn which he had caught by the tail with one of his claws, he flew into such a terrible passion that Oscar felt very glad, for the sake of the other creatures in the vase, that he was no bigger. He made up his mind to have him out before long. Except for the crab, the vase was the most charming place to live in that could be imagined, and Oscar often wished that he were able to breathe under water as easily as Theeda did, and that he were as small as she was. Theeda, no doubt, wished so too; but it was not to be. Then Oscar used to hope that, some day, Theeda would grow up to be as tall, or nearly as tall, as himself, and then come out of the water, and live with him in the cottage. But that did not seem very likely to happen either. And perhaps, after all, they were as near together as many people who live in the same house, and are separated by neither water nor crystal. Only, when Theeda brought out her oyster-shell dinner-table, and set it under the bower of green ulva leaves, and placed upon it her little cockle-shell dishes of fresh sea vegetables (which was all she ate), Oscar's very heart ached to be sitting at the opposite side of the table and dining with her. Water then seemed to him a much more agreeable element to pass one's time in than air. But, although wishing can do a great deal, it could not quite make a merman of Oscar. Theeda ate her dinners by herself except for the tit-bits that she gave to the prawns and snails, and the scraps that the fishes stole when they thought she was not looking. 'Some day, Theeda, perhaps....!' Oscar used to say, without ever finishing the sentence. Theeda understood very well what he meant, and used to look as if she meant it also. And Oscar's father, who was as powerful as he was kind, would no doubt be able to make them happy in the way they wanted, if he saw that it was best for them. But the hermit crab had a very ugly and malicious look, as if he had a mind to prevent anybody from being happy if he could. CHAPTER V. A STRANGER. One morning, while Oscar was looking into the vase, and admiring the bright silver beads that were forming all over the leaves of seaweed, and on the lichen-covered surface of the rocks; and while Theeda was busy feeding the fishes, who seemed to get hungrier the more they ate; and just when Oscar was about to remark that the hermit-crab was not in his usual hole, nor anywhere else that he could see--at that moment a dark shadow suddenly fell across the vase, shutting it off from the sunlight, scaring away the fishes, and making Theeda look up with a start, and then quickly take refuge in her shell, as from something she feared. Oscar also looked up, and saw somebody standing before the window.
